Kind Code:
A1
Abstract:
Provided is a catalyst reactor having: a reactor duct; beams horizontally stretching across; catalyst blocks each formed by incorporating a catalyst unit in a cuboid or cubic frame-shaped case; a first diversion member; a second diversion member; and a third diversion member, wherein the catalyst blocks each bridge between at least two beams and are supported by said beams, a plurality of catalyst blocks are aligned and provided inside the reactor duct such that the front surfaces and the back surfaces of the respective catalyst blocks face one another and are adjacent, and the right side surfaces and the left side surfaces of the respective catalyst blocks face one another and are adjacent, the first diversion member is attached so as to block gaps between the front surfaces and the back surfaces of the adjacent catalyst blocks from above, the second diversion member is attached so as to block gaps between the right side surfaces and the left side surfaces of the adjacent catalyst blocks from above, and the third diversion member is attached so as to cover the longitudinal direction ends of the first diversion member and the second diversion member and to block gaps between the adjacent catalyst blocks, the gaps being not blocked by the first diversion member or the second diversion member.
